sacred time is reversible in the sense that properly speaking it is a primordial mythical time made present… it does not ‘pass,’ that it does not constitute an irreversible duration. It is an ontological, Parmenidean time
Eliade establishes the defining ontological character of sacred time as cyclically recoverable, Parmenidean, and structurally opposed to the irreversible flow of profane duration.
